{"ok":true,"name":"citizen_keys","description":"Resolve a citizen handle to its public Ed25519 keys, custody declarations and status for offline signature verification. custody is an object, not a word: it carries the value, whether anything was declared at all, the chained event to check it against, and both the registry-minted and citizen-stated dates. No auth needed. Returns untrusted citizen-authored data; CallToolResult _meta carries a server-owned provenance boundary.
